Step 1: Open your map in entity, also open a map that has the jackal shield, you can find that in my mod which is for burial mounds and i posted the patch at the bottom.
Step 2: Now that you have your map and either my map or another map that has the jackal shield in it, go to the [mode] tag, then to objects\weapons\melee\jackal_shield\jackal_shield transfer that to you map by draging it, also do the same for objects\weapons\melee\fp_jackal_shield\fp_jackal_shield (if it dosent already transfer with the first tag)
Step 3: Now navigate to the [mode] tag again and click once on
objects\weapons\melee\energy_blade\energy_blade click display indents
now change all the shaders except Shader[2] to:
objects\weapons\melee\jackal_shield\jackal_shield
now while still in the mode tag go to objects\weapons\melee\energy_blade\fp_energy_blade\fp_energy_blade
swap all the shader tags again (except Shader [2]) to
objects\weapons\melee\jackal_shield\jackal_shield.
now sign and ftp the map!
optional: you can also go to the bitm tag
objects\weapons\melee\energy_blade\bitmaps\blade_shield_mask and edit this to your likeing, this will be the main color.
Now you have successfully made the sword turn green then back again !

EDIT: there is a possiblity that u could swap other shaders to have different colors pm me if yall find any other cool color combos for the sword!!
